You have to siphon the tank water into a BIG bucket and then pour it out. You can't move it from the spot so... I'm going to get like a 125 gallon in a few years so I might as well enjoy my 3.5 gallon as it is. ;P

I use a python water changer, hooks up to my sink faucet, run the cold tap on full pressure, sucks the water out. Adjust temperature once ready to refill and push the nozzle on the bottom. Takes about 20 minutes to change 75g of water in the tanks in my signature. Very easy and best $50 I ever spent (cheaper if you get the 25ft and not 50ft hose like I have)

I'm the same as Tazman, right after I set up my 46g I purchased a Python. BEST THING EVER! You hook it up to a faucet, syphon/vacuum straight to the sink, then refill it with a switch of a valve. There are other brands that i think are less expensive.

wow...Sorry I'm having a migraine and not functioning very well....You already answered my questions... My bad...

Just wanted to add my love of my Python hose. I even use it on my 10 gal betta tank that is sitting on the floor (I remove the large siphon and just use the hose and apparatus that attaches to the sink). I can't imagine doing water changes on a tank larger than 10 gallons without it. I've even used it to change water on the 120 gal NA community tank I took care of for a bit in college. I will never keep fish without this handy device.

Do they still make the python?
I broke the attachment to the sink some month's ago and could not find anywhere that still sold these.
Was told they went out of buisness.
I ended up buying Aqueon water changer which work's well but wouldn't mind finding sink adapter for my python.
Wasn't until a couple year's ago that i used these devices and i really don't know how I managed before.
Toted a lot of bucket's for larger tank's
